Multihead / Dual monitor setup

#1 Post by kenl06 »

hi there,

Im stuck at setting up my second monitor. I am using GPU (GTX1060) for my main display and onboard (intel) for my second diplay. Athough I think my system detects the second monitor, but it will not do anything about. I tried editing my xorg.conf by adding a new screen section but it gave me a black screen when i restarted and I had to uninstall nvidia driver. In my case, how do I make my second monitor work? Thanks!

I have already enabled multi monitor function in BIOS. Both screen works fine on Win 10.

f xrandr can see them both, that would be a very nice start? https://xorg-team.pages.debian.net/xorg ... randr.html

I use two cards for multihead on a fluxbox setup, but I'm not sure the big desktop environments will use multihead anymore? unless you use separate x session for each. I haven't been able to get KDE plasma to do it yet. Two outputs on the same card will probably get you further faster.

I don't use an xorg.conf until I can get them both working with xrandr, then it's easier to make the conf file. Some people say it's better to use xrandr commands in a startup script instead of xorg.conf

The xorg log is very useful to figure things out, located either in /var/log or ~/.local/share/xorg

Hi bw123. Unfortunately, xrandr doesn't show my second monitor. I will try and get another cable for my monitor so that both screens can connect to the same GPU.
